Safety precautions

The following safety precautions should be observed before using this product and any associated instrumentation. Although

some instruments and accessories would normally be used with nonhazardous voltages, there are situations where hazardous

conditions may be present.

This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions

required to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using

the product. Refer to the user documentation for complete product specifications.

If the product is used in a manner not specified, the protection provided by the product warranty may be impaired.

The types of product users are:

Responsible body

is the individual or group responsible for the use and maintenance of equipment, for ensuring that the

equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.

Operators

use the product for its intended function. They must be trained in electrical safety procedures and proper use of the

instrument. They must be protected from electric shock and contact with hazardous live circuits.

Maintenance personnel

perform routine procedures on the product to keep it operating properly, for example, setting the line

voltage or replacing consumable materials. Maintenance procedures are described in the user documentation. The procedures

explicitly state if the operator may perform them. Otherwise, they should be performed only by service personnel.

Service personnel

are trained to work on live circuits, perform safe installations, and repair products. Only properly trained

service personnel may perform installation and service procedures.

Keithley Instruments products are designed for use with electrical signals that are measurement, control, and data I/O

connections, with low transient overvoltages, and must not be directly connected to mains voltage or to voltage sources with high

transient overvoltages. Measurement Category II (as referenced in IEC 60664) connections require protection for high transient

overvoltages often associated with local AC mains connections. Certain Keithley measuring instruments may be connected to

mains. These instruments will be marked as category II or higher.

Unless explicitly allowed in the specifications, operating manual, and instrument labels, do not connect any instrument to mains.

Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test

fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than

30 V RMS, 42.4 V peak, or 60 VDC are present. A good safety practice is to expect that hazardous voltage is present in any

unknown circuit before measuring.

Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators

are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential

human contact. Product operators in these circumstances must be trained to protect themselves from the risk of electric shock. If

the circuit is capable of operating at or above 1000 V, no conductive part of the circuit may be exposed.

Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance-limited

sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective

devices to limit fault current and voltage to the card.

Before operating an instrument, ensure that the line cord is connected to a properly-grounded power receptacle. Inspect the

connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.

When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input

power disconnect device must be provided in close proximity to the equipment and within easy reach of the operator.

For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under

test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting

cables or jumpers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.

Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth)

ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the

voltage being measured.
